To @ZZ whom it may concern:

Be it known vthat I, `HENRY T. OFFTER-` DINGER, citizen of the United States',lresid ing at "Nasliiugton',` in theDistrict of Colu'mbia, have invented new and useful In1pr0vements in Portable Hot-Water Radiators, of;

which the following is a specification.

My invention relates to improvements-in seriesi'of radiatonsections,'thecombined sections'making'u' 'the radatorbeing 'ortable iacilitate Y e` circulating bod-V en'd theta radiator-su pliedlivvith my invention may have its'bo yfof circulating fluid quicklyandintensely heated."

With the foregoing object, in view the ineration is fully .met in an apvention :consists .1n -aportable hot-,water heat-. ing ap aratus or radiator possessln 'the featurls ereinater-deszr-ibed, and' i1 ustrated init eaccom an 'n 'rawings That which 'y1 g forth in the clauses-of description.:

'In the said rdrawinvs y the reference-numeral ln designates "a lhot Water radiator, which maybe ofany of the-usual known types, and` being unconnected with a-.permathe same is located.

isregarded as ne'vv will be seit anying drav-- s, illustrat' nent or stationary heating system may be, if desired, provided with an expansion box or tank 2. Through this radiator lthe water is caused Ato circulate, and the saine constitutes the effective heat radiating medium `for warming the room or other space in which Tn order to quickly and intensely heat the Water which circulates through the radiator, an additional device especially designed und calculcted to accomplish this object is provided. and combined With 'the radiator proper. Said device consists of a supplementary or auxiliary c'ircudating-,tube 3, which hereinafter 'for brevity will be referred to as a heating-tube. The

heatin -tube 3 is vertically or substantially vertica ly disposed, lso that there is an up- Wardlowoi the hereinafte1referred-to fluid column therethrough.- The term vertical or substantiallyvertical is-employed to I convey theidea of Ithis' u Ward How of the fluid colurnnuand is inten ed to include the substantial functional eqivalentjof the arrangement shown. The said4 tube is in cornmnn'ication .at its oppositeends with the .fluid-circulating system oflthe radiator by means of suitable couplings or connections 4 and is essentially of such construction or conformation as will compel the fluid passin therethrough to assume a film form, in whic 4 form the fluid body ma be most quickly or readil and intensely cated.` To the' accomp shment of this end, the said auxiliary .or su pleme'ntary tube comprises opposite para] e Walls' 5,. closelyassociated and resentingrelatively broad or extended su ace areas vcapable of being" subjected tothe in 'fluence of a heating medium and compelling fthe water whichpasses. therethrough to conform to the characteristic .contour of the said vsupplementary or auxiliary heating-tube and -assume the form of a Huid lmfthe attenuL 'ated characterof which is most susceptible of responding to the inuence of heat applied to the tube through which it passes.

respect to closeness' to each other than do they Walls of the columns of the radiator 1.,

The vbroad flat .parallel Walls'of theheatf.v ,ing-tube sustain a relatiommore intimate 1n' IOO and the circulation ca acity of said heating- Itube is sufficient to ta e care-of the circulat-y y ator, so that the column of water passing inicapacity of the several columns of saldi ra from the eutlet'end of the radiator is changed as to its form and made to come to a thin or film-like column by reason of the characteristic construction of the heating-tube. In this form the thin film-like column of water passing through the heating-tube presents a great surface area as compared'with the mass of the column to the influence of the burner next to be described. The Huid column maintains the film-like form referred to throughout the heating-tube and in such form is subjected to the direct influence of the burner. Preferably and as shown the heating-tube is a vertical one, in which form it is considered that the greatest efficiency is secured. -This may beI attributed to the -probable formation of a thin stratum of va or along the interior wall of the heatingtu e, tending' to travel rapidly through the tube and exerting an accelerating influence on the fluid column within the tube.

Associated or combined with the auxiliary or supplementary heating-tube is a burner 6, the jet-orifices 7 of which extend across and in nearness to the parallel walls of the tube. This burner entirelysurrounds the tube-and is preferably and as shown of the Bunsen r type, having a conduit 8 for the supply of fuel, such as gas, and a regulable means 9 for the supplyl'of atmospheric air. The fuel may be oil or gas, as may be desired= For the purpose of confining the flame of the burner to exert its greatest efficiency upon the tube and itscontents a jacket 10, conforming to the external conguration of the tube, is pro- .vided surrounding the said -tube .and supported .in suitable manner from theburner,

, as shown, having a slip fit about a preferably continuous flange 11, with which the burner 1s provided. The jacket at its lower end adjacent the jet-orifices of the burner is provided withpopenings .12 for theample supply `of oxygenv to support combustion, and at its upper end 1s provided with a slip-cap 13,

,havingv openings 14, adapted to more or less register with, and therefore more or less open or entirely close, similar openings 15 in the. i

jacket for the purpose ofi regulating the draft., By making lthe jacket conform to theshape ofv the heatinG-tube the products oflconibustionare caused to impinge directlyA and equally against the walls oftheheating-- tube, and' saidjacket is4 closely associated with ythefhe'ating-tube, a comparatively narrow s ace intervening between the-same, so

Y that t ie maximumheatin'g effect is secured.

l In .the practicaluse of portable hot-water radiators according tmy invention means are provided Whereb .connection .may be 'made fromeither en of the burner." i Frev uently by reason yofflocal surroundings raiators cannotwithf'facility be used, because of thedifliculty ofi-connecting the same with the fuel-supply. According to my invention ,the burnerisfprovided'with a duplexorplural lmeans 16 of connection with the fueld supply, either of which means may be closed by a cap 17'., and the other or either of which may be connected with the fuel-supply. By

the plural fuel-supply radiators embodying e Want is fully sup` lied by iny invention.l

Having thus descri ed my invention, what I claim is- 1Qv In combination with a portable hotwater radiator, a vertically-disposed supplemental or auxiliary heating-tube having communication with the fluid-passages of the radiator and comprising walls which, as compared with the walls of the columns of the radiator proper, are closely associated to compel the uid to pass therethrough iii a thin ihn, a burner combined with and surrounding said heating-tube at the lower portion thereof, and a heat-confining jacket associatedv with the burner and surrounding the heating-tube. y

2. In combination` with a portable hotwater radiator, a vertically-disposed supplev mental or auxiliaryheating-tube having coinmunication'with the fluid-passages of the radiator and comprising walls, which, as compared with the walls of the radiator proper, are relatively closely associated-to 'compel the fluid to pass therethrough in a thin film, aburner combined with and 4surroundii'i@r said heating-tube at the lower end thereof and a heat-confining a'cket surrounding and conforming to the shape of said heating-tube.
